algorithmic modeling for Rhino
Hi to all :)
Is there any component that draws an ellipse from 2 focal points and the sum of distances from that focal points?
Thanks in advance :)
With a plenty of geometrical research, i compose the component to make an ellipse, given with the focal points and tickness of the ellipse.
After that, when i was trying a solid union operation, I found that in the very first ellipse (that i was trying to make it with deformation of sphere) could do the trim. But second eliipse (which is perfectly arrenged) couldnt do that operation.
Can somebody help me where i was wrong?
this is the main object;
This is the first ellipse that i did it with deformation of sphere;
and this is the subtraction which is true..;
the mistake is that you're revolving the whole ellipse with an angle of 2*Pi. If you use only half of the ellipse curve to revolve, it works. I matters which half you pick. In the file you attached, use the SubCurve component after the ellipse, and use domain 0.5 To 1 (reparameterize the curve first). Check the resulting Brep to be sure its normals are pointing out.
(In fact I did make the component you discribed, and while it's working great over here:), I'm not sure it's 100%. But if you'd like to try it: just ask)
THANK YOU SOOO MUCH!!!
I appreciate :)))
your component is charming :)
You're welcome, I think you wrote that you'd like to try it, or?
They'll show up in the Curve> Primitive Tab, please let me know if they're any good.
I keep getting the error that I must provide 2 foci, when I am providing two points as foci. Would you mind sharring the source code?
Hi Philip, the F input takes a list of two points (per ellipse),
so in case of just one ellipse, just flatten the input.
it should be introduced as standard gh component.
